Problems solved by technology

[0004] However, the water-based thin steel structure fireproof coatings currently produced in China generally have shortcomings and problems such as poor fireproof performance, low expansion ratio of the expansion layer, low structural strength, and poor water resistance of the coating film. At the same time, the existing water-based thin steel structure fireproof Coatings also do not have the function of radiation protection, so it is difficult to use them in nuclear buildings
It is an urgent task for technical workers in the art to develop a water-based coating with long flame retardant time, high viscosity and cohesive strength, relatively long drying time, no pollution, no fire hazard, production cost, convenient production and construction, and good radiation protection performance. problem to be solved

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a fireproof and radiation-proof coating for thin steel structures. Background technique [0002] With the development of industrialization, especially in the construction of large and medium-sized cities, steel structures have become a very important construction application material due to their fast and convenient construction advantages. As metal steel structures, they are mostly used in standard In factories, large stadiums, airports, bridges, three-dimensional garages and nuclear buildings. However, the fire resistance of steel structures is far inferior to that of brick-concrete structures. The critical temperature of steel is 540°C. When this temperature is reached, its bearing capacity will be reduced by about half. In a general fire, this temperature can be reached in about 15 minutes, leading to the collapse of the building. This charac...
